Tax Specialist – AI Trainer

Freelance | 8–20 hrs/week | Remote (EU/UK)

Are you a tax specialist who wants to apply your expertise in a new way?

Do you have 8 to 20 hours per week available alongside your current role or advisory work?

We are looking for experienced tax professionals based in the EU or UK to help improve advanced AI systems.

What you’ll be doing

We are 10x.team, a platform for fractional and freelance professionals. We partner with leading AI labs to improve large AI systems.

Your role is practical and high impact. You will:

• Review and refine AI generated responses related to corporate tax, VAT, transfer pricing and international tax matters

• Evaluate outputs for technical accuracy, regulatory alignment and risk awareness

• Draft realistic tax scenarios such as cross border structuring, permanent establishment analysis, VAT treatment questions, tax audits, dispute resolution or transaction structuring

• Create variations of the same scenario from different perspectives such as tax advisor, CFO, regulator, auditor or business owner

• Identify weaknesses in tax logic, misinterpretation of legislation, incomplete risk analysis or unrealistic structuring assumptions

In simple terms:
You will assess and improve AI generated content to ensure it reflects real world tax reasoning, legislative interpretation and practical risk considerations.

This is not tax compliance execution. Instead of preparing returns for individual clients, you will help improve how AI systems understand and reason about tax law and structuring at scale.

Your input directly improves how AI performs on tax and fiscal topics.

You are:

• A tax advisor, tax consultant, corporate tax specialist or indirect tax professional

• Based in the EU or UK

• Able to start in the coming weeks

This role is fully remote and flexible.
It works well alongside your existing professional commitments.

Why join

• Flexible hours

• Fully remote

• Apply your tax expertise in the field of AI
